[PATCH 1/3] CRIS: UAPI: fix ptrace.h

[PATCH 1/3] CRIS: UAPI: fix ptrace.h

[Rabin Vincent]

The exported ptrace.h header on CRIS references an "arch" directory
which does not exist.  Fix this by having the variants in the same
directory and including them conditionally, similar to other
architectures.

[PATCH 2/3] CRIS: don't make asm/elf.h depend on asm/user.h

[Rabin Vincent]

We're going to export asm/elf.h; remove its dependencies on the
non-exported asm/user.h and the unused asm/system.h include.

[PATCH 3/3] CRIS: UAPI: fix elf.h export

[Rabin Vincent]

CRIS userspace (uClibc for one) expects asm/elf.h to be exported but
this header appears to have gone missing at some point.  Move it to
uapi/ and export it.
